This function checks if the two input intervals oferlap and outputs the corresponding pattern (up, down, or straight) based on that.

Usage

determine_uds(min1, max1, min2, max2)

Arguments

min1, max1, min2, max2

the endpoints of the two intervals

Value

A single character (one of "U", "D", "S") representing the pattern

Examples

determine_uds(10, 20, 15, 25) # overlap
#> [1] "S"
determine_uds(10, 20, 25, 35) # no overlap
#> [1] "U"
